- The Mexico–United States border (Spanish: frontera Estados Unidos–México) is an international border separating Mexico and the United States, extending from the Pacific Ocean in the west to the Gulf of Mexico in the east. The border traverses a variety of terrains, ranging from urban areas to deserts. It is the most frequently crossed border in the world with approximately 350 million documented crossings annually. Illegal crossing of the border to enter the United States has caused the Mexico–United States border crisis. It is one of two international borders that the United States has, the other being the northern Canada–United States border; Mexico has two other borders: with Belize and with Guatemala.
- Douglas Creek (Washington) (Wikipedia)
Douglas Creek is a creek in Douglas County, Washington. It rises in Douglas County, flows through Moses Coulee then empties to Wanapum Lake on the Columbia River. The course of the creek through Moses Coulee displays an “outdoor geologic laboratory” exhibiting basalt formations and relics of the Missoula floods of the last ice age. The watershed of Douglas Creek proper covers 132,056 acres (53,441 ha), about 11% of the county, but including McCarteny Creek the entire Moses Coulee drainage is 1,000 square miles (2,600 km2) or a little more than half of the county. The creek’s flow reaches the Columbia River “during storm water runoff events”, otherwise being absorbed into the aquifer.
